Pyrex containers are literally the best out there. My family owns a TON of Pyrex stuff, and it really does lasts forever. It's great for storing anything and makes for an easy reheat too, because it's glass. I definitely recommend Pyrex products.

Make sure it is "Borosilicate glass". Corning sold the Pyrex brand to World Kitchen in 1998 and they started marketing Pyrex as pre-stressed soda-lime glass.

This from Popular Science:
"Pyrex, which originally was always borosilicate glass, solved this problem by adding boron to the silica (quartz), the main ingredient in all glass. Boron changes the atomic structure of glass so it stays roughly the same size regardless of its temperature. Little thermal expansion means little stress. Thus borosilicate glass withstands heat not because it’s stronger, but because it doesn’t need to be stronger."

"When World Kitchen took over the Pyrex brand, it started making more products out of pre-stressed soda-lime glass instead of borosilicate. With pre-stressed, or tempered, glass, the surface is under compression from forces inside the glass. It is stronger than borosilicate glass, but when it’s heated, it still expands as much as ordinary glass does. It doesn’t shatter immediately, because the expansion first acts only to release some of the built-in stress. But only up to a point."

i got this set during the 'blue christmas' side-woot, only the lids weren't blue. customer service sent out another one (with "blue" clearly printed on the packing slip), and they wasn't blue either. i'm sure this only matters to me, but will this set be blue?

If this is something you want, but don't NEED. Amazon sells these now and again for $16 with free shipping / prime new, and even more rarely you'll see the 14 and 18 piece sets via Warehouse Deals for < $10 (I paid $7.05 for a 14 piece round set at the end of last november)

At the moment amazon won't sell these ("Item Under Review

While this item is available from other marketplace sellers on this page, it is not currently offered by Amazon.com because customers have told us there may be something wrong with our inventory of the item, the way we are shipping it, or the way it's described here. (Thanks for the tip!)..." so I can't tell you the current price.

That said, these are pretty awesome, we have lots of leftovers, and 1 18 piece,1 14 piece, and 1 10 piece do our little family of 3 quite nicely. Just treat them carefully and you'll be quite happy.

World Kitchen refuted that, http://www.pyrexware.com/index.asp?pageId=30 and claim that since the 1940's, all Pyrex cookware has been made with soda-lime glass, and the borosilicate was used from the founding of Corning in 1915 until the 1940's.

I wonder if the higher rate of of incidents is because many more people have granite countertops. Seems from the video granite may cool the dish down faster or people are dropping hot dishes right onto the granite.

I got a set of these and love them. The lids have held up, maybe because I wash them by hand. Also, they take up relatively little space, especially if you stack them the way they packed them in the shipping box (larger bowl with smaller lid inside and on bottom then coordinating bowl, etc).

I bought this set from Woot a few months ago. 3 of the bowls came shattered in the box when i received them. Pyrex needs to do a better job at packing glass because we all know packages like this get tossed around like beach balls in transit.

I bought this same set off of a Woot Off a few months ago. Be sure to inspect them thoroughly because the package handlers were rough with mine and some were chipped. I reported it to Woot and they were very helpful and issued a refund.

I have used these for years (the same set) and never had any problems. We use them in the freezer, oven, microwave, fridge.

I have dropped these many times from the counter top and they bounce and never had one break yet. My floor is not tile or stone though so YMMV.

Someone asked if they stack. Well in a way they do, but not like plastic. You can fit the same size bowl inside another and it will fit this is what we do. We can stack this set with 2 columns in our cabinets. Same with the rectangle set.
